Structural rigidity would rely to some extent on the structures they would be attached to as well as their complex geometries and interconnections. 辅助层结构的刚性在某种程度上取决于它们附着建筑物复杂的几何形状和建筑物间如何相互连接的。
Another area of attention is the upgrading of the electrical grid so that it can accept interconnections from distributed solar systems. 另外一个需要关注的领域是电网的升级，这样才能实现与分布式太阳能系统的相互连接。
